A compressor rotor for turbomachinery, such as a centrifugal compressor, is provided. Disclosed embodiments include a tie bolt and a rotor shaft that cooperates with the tie bolt to define a chamber therebetween. A seal assembly is positioned to separate the chamber from a first space and a leak detector in fluid communication with the first space and operable to generate a signal indicative of leakage of a fluid from the chamber to the first space.

In a turbomachine, rotor structure with seal assembly and method in connection with same

Compressor rotor structure and methodology for harmonizing compressor aerodynamics and rotordynamics are provided. Disclosed embodiments benefit from a compressor design effective for improving rotordynamics (e.g., stiffer rotor structure) without reducing a usable aerodynamics range of the compressor. This design may involve variation of the rotor structure along the rotor axis to locate respective surfaces defined by respective inlets of the one or more impellers at a varying distance relative to the rotor axis based on respective ratios selected for the configuration of the impeller bodies. This arrangement may be effective for improving rotordynamics while satisfactorily meeting the respective varying aerodynamics requirements at the various compression stages by the impeller bodies.

Compressor rotor structure and method for arranging said rotor structure

Compressor rotor structure for turbomachinery, such as a compressor, is provided. Disclosed embodiments can benefit from sealing sleeves that may be arranged to inhibit passage onto respective hirth couplings of process fluid being processed by the compressor. The sealing sleeves may be affixed to adjoining structures (e.g., adjoining impeller bodies) by way of a slip fit connection to one of the adjoining structures and an interference fit connection with respect to the other adjoining structure, which is conducive to a user-friendly assembly of the sealing sleeves with the adjoining structures.

Compressor rotor structure

A turbomachine housing, in particular of a radial turbomachine which transfers technical work to a process fluid or from a process fluid, includes: an opening extending along an axis, for the axial feed-through of a shaft extending along said axis; a contact surface extending along a circumferential direction with respect to the axis, for contact with a housing jacket of the turbomachine housing. A flow line provided as an inflow or outflow of the process fluid is designed as an integral part of the cover.

Turbomachine housing having at least one cover, turbomachine, method for producing a cover

A turbomachine, in particular, a compressor, having a housing and having at least one housing insert accommodated therein and having a fitting piece for the adjustment of a gap dimension between the housing and the housing insert, wherein the housing comprises, for the adjustment of the gap dimension, a horizontally adjustable guide element into which the fitting piece is inserted, is provided.

Turbomachine with gap adjustment

A turbomachine foot unit with a plurality of feet is provided. The plurality of feet is fastened to a turbomachine. The turbomachine stands upright on a horizontal base. The turbomachine foot includes fastening devices for fastening the feet to the base. At least one of the feet is mounted in a horizontally moveable manner relative to one of the fastening devices fastening the foot to the base.
